Forerunner® 165 Music — Frequently Asked Questions

Will the Garmin Forerunner® 165 Music fit my wrist?

The Garmin Forerunner® 165 Music looks balanced on flat wrist widths of roughly 45–61mm (about 12.0–16.3cm circumference). Drag the slider above to check it against your own measurement.

How long does the Garmin Forerunner® 165 Music battery last?

Between 6.5 hours and 20 days per charge, depending on the power mode. Garmin rates Battery Saver Smartwatch at 20 days and All-Systems GNSS with music at 6.5 hours; the chart above lists all 6 modes.

How does the Garmin Forerunner® 165 Music battery compare with other Garmin watches?

At 11 days in everyday use it ranks #166 of the 257 Garmin watches in our database — below the middle of the range. The full ranking, including GPS and power-saving figures, is on our Garmin battery life comparison.

Is the Garmin Forerunner® 165 Music thick for a 43mm watch?

At 11.6mm, thinner than 86% of 43mm watches, so it slides under a cuff more easily than most of its size. Thickness, not case width, is what decides whether a watch catches on a shirt cuff.

What other watches are the same size as the Garmin Forerunner® 165 Music?

OnePlus Watch 3 43mm, Oppo Watch X2 Mini, Omega Speedmaster Moonphase Stainless Steel / Black Meteorite / Bracelet, Zenith Defy Extreme Diver Shadow / Bracelet all sit within half a millimetre of the Garmin Forerunner® 165 Music's 43mm case, so they cover the same amount of wrist.
